About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-40
The AirTAC SAIJ32X290-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window between 250 and 290 mm without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This configuration uses a SUS304 stainless steel rod for corrosion resistance and PT tapered port threads. The 12 mm rod and M10x1.25 thread provide a robust interface, though the 290 mm stroke length means an external guide is recommended to manage side loading. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-40 Is Used
Machine Changeover
Dial in the 250-290 mm travel window during product size transitions to set new end positions without physically swapping cylinders.
Variable End Stops
Use the 40 mm rear adjustment screw to fine-tune the retract position precisely during machine commissioning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-40 the Right Cylinder?
If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N. The SAIJ design is selected over a fixed-stroke SAI when product changeovers demand variable end-stops, letting you dial in the exact 250-290 mm travel window on the fly.
As a dimensionally interchangeable ISO 15552 cylinder, replacement requires matching the 32 mm bore, 290 mm stroke, 40 mm adjustment range, PT G1/8 port, and the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this plain SAIJ lacks a magnet; for position sensing you would need an -S variant fitted with AirTAC CMSE reed or DMSE electronic sensors. Because the stroke is over 300 mm, ensure an external guide supports the load to prevent rod bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-40 FAQ
The rear adjuster screw lets you shorten the 290 mm nominal stroke by up to 40 mm, creating a usable travel window of 250 to 290 mm. It functions as a physical stop and does not lock the load without continuous air pressure.
